that's very sweet to think of, bob. to play a concluding section. it's hard if they are right in the middle of the development - but not impossible. i mean, when i think about this one girl right now (a violinist) - she was so embarrassed and i really didn't know what to do and hoped she would come in again. but, the longer she stood there, and the longer i played - the worse it got. so i stopped. but, if i had played a conclusion - it might have been better for her? i think so!
